Background technology
At present, at home in existing tunnel Project Shield machine, the topping machanism of shield machine is to be pacified by cutterhead body with fixed
The various cutters of dress in the above collectively constitute, and during tunnelling, the size of tunnel diameter is by being configured on cutterhead
The radial dimension of edge doctor control.Edge doctor is fastened by bolts on tool rest in the prior art, knife of backbreaking fixed setting
On tool rest, the tool rest is directly welded at the periphery of cutterhead body, therefore the edge doctor on cutterhead body and knife of backbreaking are excavated
Diameter immobilize, it is impossible to according to the radial dimension of the excavation of geological state and requirement of engineering adjust automatically edge doctor.Compared with
Long excavation section, often there is the situation of edge doctor abrasion, cause cutterhead digging diameter to reduce, such case can bring following ask
Topic：The increase of shield body frictional resistance, or even there is " card shield " phenomenon；The abrasion aggravation of cutterhead body large circle, easily causes cutterhead body
Damage；Shield machine fltting speed reduces, or even can not normally tunnel.As defined in therefore as long as the digging diameter of edge doctor is reduced to
Threshold value, it is necessary to change digging diameter that edge doctor just can guarantee that cutterhead in scope of design, can so cause edge doctor to change
Frequency increases, therefore the problem of taking a lot of work, be time-consuming, cost is high be present.Also, all it is due to changing edge doctor operating personnel every time
" with pressure " to enter in soil cabin, frequently changing edge doctor can cause personal safety hidden danger high.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of development machine that can be adjusted and radially excavate size
Topping machanism, ensure the digging diameter of cutterhead in scope of design, to solve in the prior art because edge doctor abrasion easily causes
The problem of shield body card shield, while solve, because edge doctor is changed often, to cause the problem of maintenance cost is high, and potential safety hazard is big, together
When the utility model additionally provide a kind of development machine, ensure that being smoothed out for headwork.
In order to solve the above technical problems, the technical scheme that the topping machanism of development machine of the present utility model uses is：This reality

The moving direction of lever 5 is more accurate, ensures the constant relative to the position of cutterhead of edge doctor 14, and the dynamics and side for ensureing cutting are scraped
The precision that knife 14 compensates.
It is further preferred that the limitation tool rest 12 that the topping machanism of the present embodiment also includes setting on knife beam 17 excessively moves
Position-limit mechanism.Specifically, position-limit mechanism is included across in the top of guide groove and the spacer pin 6 that is installed on guide pad 7.Limit
Position pin 6 is to be installed to by following structure on guide pad 7, and the limit pin hole penetrated for spacer pin 6 is provided with guide pad 7
8, after spacer pin 6 is penetrated into limit pin hole 8, spacer pin 6 is pressed abd fixed in limit pin hole 8 by a cover plate 10, cover plate
10 are fixed on guide pad 7 by bolt 9.The Stop structure coordinated with the block of spacer pin 6 is provided with drive link 5.
Further preferably it is configured, above-mentioned Stop structure is the spacing logical of the receiving spacer pin 6 that the upper surface of drive link 5 is set
Groove 11, the groove width between two walls of spacing groove 11 are the diameter of spacer pin 6 and the maximum overhang sum of edge doctor 14, limit
The stopping surface that the two side of position groove 11 coordinates for the outer wall block when spacer pin 6 moves with spacer pin 6.
Edge doctor 14 is protruding under the drive of drive link 5, can not be further continued for stretching out compensation when edge doctor 14 may wear to
During wear extent, now edge doctor 14 reaches maximum wear extent, and spacer pin 6 is contacted with the rear wall block of spacing groove 11, prevented
Because drive link 5 continues to stretch out, other accessories such as abrasion tool rest 12.Because position-limit mechanism is spacing using spacer pin and spacing groove
Coordinate, mechanical block position limiting structure, simple in construction, security reliability, Maintenance free, and service life is grown.
Touch sensor can be set on the rear wall of spacing groove 11, when the overhang of edge doctor 14 reaches maximum,
Spacer pin 6 contacts with the rear wall block of spacing groove 11, and spacer pin 6 touches touch sensor, and touch sensor is by signal
Control centre is transferred to, prompts edge doctor to need to change, control centre receives the signal and sends the instruction for changing edge doctor.
Certain control centre can also take other modes to judge whether to need to change edge doctor, for example, can basis
The modes such as the drag size that the overhang for measuring the expansion link of telescoping cylinder, the expansion link for measuring telescoping cylinder are subject to.
It is further preferred that being installed with block on tool rest 12 between the side wall of tool rest 12 and knife beam 17, knife beam 17 is kept
Inside and the block part 16 of outside seal isolation.After edge doctor 14 stretches out, between the front end face of edge doctor 14 and knife beam 17
A gap can be formed, block part 16 stretches out with edge doctor, can close the gap, ensure that the inside and outside of knife beam 17
Seal isolation, effectively prevent debris from entering inside knife beam 17, avoid influence telescoping cylinder 1 normal operation.
In other embodiments, as shown in figure 4, above-mentioned telescoping mechanism can also take motor driven crank connecting link machine
Structure realizes the movement of tool rest, and motor 20 is arranged on the rear back side of cutterhead, is provided with shifting chute 22 on knife beam 17, in shifting chute 22
